TECHNICAL FIELD

[0002] The present invention relates to the field of communication technologies, in particular, it relates to a hybrid automatic repeat request feedback method (HARQ), a method for sending indication information, and a user equipment (UE), and a base station thereof.

BACKGROUND

[0003] With the development of communications technologies, 5th Generation (5G) mobile communication technology has been developed. Types of service on 5G at least include enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra secure low latency communication (URLLC), and the like. These types of services all belong to data services, but impose different requirements on latency and reliability. For example, the URLLC service is applied in fields such as the Internet of vehicles where low latency is required. This service imposes a stricter requirement for punctuality, and requires the establishment of a punctual service, or even prevails over the original services. The mMTC service is not sensitive to latency, and in this service, data can be transmitted over a longer period of time. One way to implement effective transmission of latency-sensitive services is to improve the transmission of a hybrid automatic retry request (HARQ), such that, for example, retransmission feedback is faster and more accurate.

[0004] In Long Term Evolution (LTE), Feedback HARQ is carried out with a transmission block (TB) as a unit and each TB feeds a 1-bit acknowledgment (ACK) or non-acknowledgment (NACK) message . To improve retransmission accuracy, 3rd Generation Partnership Project (3GPP) has proposed retransmission based on a code block group (CBG). CBG is an even smaller data unit in TB. A CBG corresponds to 1-bit ACK or NACK feedback. Since the granularity of the retransmission is even less, the position of an incorrect transmission can be more precisely reflected, such that the retransmission is more accurate. Additionally, since the retransmission requires even less data, the retransmission efficiency is higher.

[0005] However, in the case of a service preemption, for example, when the eMBB service is being transmitted or is to be transmitted, the URLLC service is approaching, the URLLC service may take precedence over the transmission of time-frequency of the eMBB service. As a result, the original eMBB service may mistakenly consider that eMBB data is incorrectly transmitted in an HARQ feedback process, and, consequently, useful URLLC data may be discarded.

DETAILED DESCRIPTION

[0055] In order to describe the principles, technical solutions and advantages in the embodiments of the present clearly and completely, the present invention will be described in detail below in combination with the accompanying drawings. Apparently, the described embodiments are merely some embodiments, preferably of all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments derived by a person skilled in the art without creative efforts should fall outside the scope of protection of the present invention.

[0056] FIGURE 1 is a flow chart of an HARQ feedback method according to an exemplary embodiment of the present invention. This embodiment is described on one side of the UE. As illustrated in FIGURE 1, the HARQ feedback method includes the following steps:

[0057] In step S101, a first service data transmission is received from a base station, where program control data from the first service data transmission carries indication information, and the indication information explicitly or implicitly indicates that second service data prevails over a first service data transmission resource, or second service data prevails over a position of the first service data transmission resource.

[0058] In this embodiment, a first service imposes a higher request for punctuality related to a second service, and therefore, the first service data can prevail over the first service data. The first service can include, but is not limited to, eMBB, and the second service can include, but is not limited to, URLLC.

[0059] When a UE receives a first service data transmission from the base station, the indication information can be carried in the program control data of the first service data transmission, where the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data, or the second service data prevails over the position of the transmission resource of the first service data. When the UE receives the first two service data transmissions from the base station, the indication information can be carried in the program control data of a first later service data transmission, where the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data, or the second service data takes precedence over the position of the transmission resource of the first service data in a first previous service data transmission. Program control data may include, but is not limited to, a physical downlink control channel (PDCCH). It should be noted that in the latter case, a time interval between the first two service data transmissions is less than a transmission latency in a non-adaptive HARQ feedback mode; and, otherwise, before the program control data of the first subsequent service data transmission comes, necessary HARQ feedback information is sent to the base station. That is, the UE needs the HARQ feedback information for the base station before receiving the indication information.

[0060] In step S102, the second service data that prevails over the transmission resource is retained in a cache according to the indication information, and HARQ feedback information from the first service data is generated.

[0061] In this embodiment, the second service data that prevails over the transmission resource can be retained in a cache according to the indication information, for transmission of the second service data.

[0062] The HARQ feedback information can be generated in a plurality of ways. For example, HARQ feedback information can be generated based on a transmission success or data failure state other than the second service data that prevails over the transmission resource. For example, a transmission success or failure state of the second service data that prevails over the transmission resource can be adjusted as a transmission success, and the HARQ feedback information is generated according to the transmission success or status. all data failures in the first service data transmission.

[0063] The HARQ feedback information generated may correctly reflect the success of transmission or failure status of the first service data, such as incorrect operations.

[0064] In step S103, the HARQ feedback information is sent to the base station.

[0065] In this embodiment, when the indication information is carried in the program control data of the first subsequent service data transmission, the HARQ feedback information can be sent to the base station in the non-adaptive HARQ feedback mode.

[0066] In the above embodiment, upon receipt of the indication information carried in the first transmission of service data, the second service data that prevails over the transmission resource are retained in the cache, such that the second useful service data cannot be discarded during the first service data transmission.

[0067] FIGURE 2 is a flow chart of a method for sending indication information according to an exemplary embodiment of the present invention. This embodiment is described on one side of the base station. As illustrated in FIGURE 2, the method includes the following steps:

[0068] In step S201, if second service data prevails over a transmission resource of first service data, they are inferred.

[0069] The first service can include, but is not limited to, eMBB, and the second service can include, but is not limited to, URLLC. A first service imposes a higher request for punctuality in relation to a second service, and therefore the first service data can prevail over the first service data. In this embodiment, the base station can infer whether the second service data prevails over the transmission resource of the first service data.

[0070] In step S202, if the second service data prevails over the transmission resource of the first service data, a first service data transmission is sent to a UE, in which the program control data of the first service transmission service data carries indication information, and indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data, or the second service data prevails over a position of the transmission resource of the first service data, such that the UE sends HARQ feedback information from the first service data to a base station based on the first indication information.

[0071] In this embodiment, if the base station determines that the second service data prevails over the transmission resource of the first service data, the indication information can be carried in the program control data of the first service data transmission sent to the UE. The indication information can give an explicit indication, for example, several bits of indication information can be added directly, or the indication information can give an implicit indication, for example, the indication information is encrypted in the target control information in the program control data, that is, the corresponding indication information is encrypted in a portion of the original control information. The indication information may indicate that the second service data takes precedence over the transmission resource of the first service data, or the second service data takes precedence over the position of the transmission resource of the first service data, where the position of the resource transmission can be indicated by a bitmap. Upon receipt of the referral information, the UE can retain the second service data that prevails over the transmit resource in a cache according to the referral information, and sends the HARQ feedback information from the first service data to the base station .

[0072] The sending of the first service data transmission by the base station to the UE may include: sending a first service data transmission by the base station to the UE. In this case, the indication information can be carried in the program control data of a first service data transmission, and the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data. service, or the second service data prevails over the position of the transmission resource of the first service data.

[0073] In addition, sending the first service data transmission from the base station to the UE may additionally include: sending two first service data transmissions from the base station to the UE. In this case, the indication information can be carried in the program control data of a first subsequent service data transmission, and the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first data service, or the second service data prevails over the position of the transmission resource of the first service data in a first previous service data transmission.

[0074] Program control data may include, but is not limited to, a physical downlink control channel (PDCCH).

[0075] It should be noted that in the latter case, a time interval between the first two service data transmissions is less than a transmission latency in a non-adaptive HARF feedback mode; and otherwise, before the program control data of the first subsequent service data transmission comes, feedback information HARQ needs to be sent to the base station. That is, the need for the UE to send the HARQ feedback information to the base station before receiving the indication information, that is, the UE fails to prevent incorrect operations based on the indication information.

[0076] In the above embodiment, when it is determined that the second service data prevails over the transmission service of the first service data, the first service data transmission that carries the indication information is sent to the UE, to notify the UE that the second service data prevails over the transmission feature of the first service data, such that incorrect UE operations can be prevented.

[0077] FIGURE 3 is a signaling flow chart of an HARQ feedback method according to an exemplary embodiment of the present invention. This embodiment is described from a perspective of interactions between a UE and a base station. For clearer descriptions of the interactions between the UE and the base station, this embodiment is described with reference to FIGURE 4. FIGURE 4 is a schematic diagram illustrating what indication information is carried in an eMBB transmission process according to one embodiment exemplary of the present invention. As illustrated in FIGURE 4, the indication information is carried on a PDCCH of an eMBB data transmission. As illustrated in FIGURE 3, the HAQR feedback method includes the following steps:

[0078] In step S301, when the base station determines that URLLC data prevails over an eMBB data transmission resource, the base station sends an eMBB data transmission to the UE, where the eMBB data transmission carries indication information.

[0079] The referral information may explicitly indicate that the URLLC data prevails over the eMBB data transmission facility, or the URLLC data prevails over a position of the eMBB data transmission facility.

[0080] In step S302, the UE receives the transmission of eMBB data from the base station, and retains the URLLC data that prevails over the transmission resource in a cache according to the indication information carried in the PDCCH of the data transmission eMBB, and generates HARQ feedback information from the eMBB data.

[0081] When the referral information explicitly indicates that the URLLC data prevails over the eMBB data transmission facility, the UE can retain all data that fails to be transmitted in the cache, identifies the eMBB data that fails to be transmitted from the retained data, and generates HARQ feedback information based on the eMBB data that fails to be transmitted.

[0082] For example, the UE may retain data corresponding to all transmission resources with NACK feedback in the cache, and may not align the data. After all URLLC data has been transmitted, useful URLLC data in the retained data is used. If some data remains, except the data used, this indicates that the data is the data that truly fails to be transmitted, and the UE can calculate the HARQ feedback information based on the data.

[0083] When the referral information explicitly indicates that the URLLC data prevails over the position of the transmission resource of the eMBB data, the UE may retain the URLLC data that prevails over the transmission resource in the cache for transmission of the data of eMBB URLLC, and other data with NACK feedback can all be aligned. In addition, the UE can generate HARQ feedback information based on a transmission success or data failure state other than the URLLC data that prevails over the transmission resource. For example, the UE can generate HARQ feedback information based on a transmission success or failure state of eMBB data from a code block group (CBG) other than a CBG 4.

[0084] In step S303, the UE sends the HARQ feedback information from the eMBB data to the base station.

[0085] In step S304, the base station retransmits the eMBB data that fails to be transmitted to the UE based on the received HARQ feedback information.

[0086] Optionally, when the indication information indicates that the second service data prevails over the position of the transmission resource of the first service data, the base station can receive the HARQ feedback information from the first service data of the UE, in that the HARQ feedback information includes HARQ feedback information of the second service data corresponding to the position of the transmission resource, and HARQ feedback information of the first service data corresponding to the other positions of the transmission resource; and retransmitting the first service data that fails to be transmitted to the UE according to the HARQ feedback information from the first service data corresponding to the other positions of the transmission resource. That is, when it is determined to retransmit the first service data, the base station ignores the HARQ feedback information from the second service data corresponding to the position of the transmission resource, but only considers the HARQ feedback information from the first service data corresponding to the other appeal positions.

[0087] For example, the base station can determine that the eMBB data is retransmitted according to the HARQ feedback information of the eMBB data corresponding to the CBG other than CBG 4, as illustrated in FIGURE 4.

[0088] In the above embodiment, based on the interactions between the UE and the base station, the UE may recognize that the URLLC data prevails over the eMBB data transmission facility, such that the UE may not discard the useful URLLC data during the transmission of eMBB data, and can correctly feed back the successful transmission or failure state of the eMBB data to the base station. In this way, the base station can relay the eMBB data that truly fails to be transmitted.

[0089] It should be noted that with respect to a base station having the ability to infer that the second service data prevails over the first service data, HARQ feedback can be generated based on the process as illustrated in FIGURE

3. However, with respect to a base station that does not have such capacity, the inference can be practiced based on the indication information carried on the PDCCH of the first subsequent service data transmission. The indication information can explicitly or implicitly indicate that the second service data prevails over the transmission resource of the first service data, or the second service data prevails over the position of the transmission resource of the first service data in the first transmission of data. previous service data. The first two transmissions of service data can be contiguous or non-contiguous.

[0090] FIGURE 5 is a signaling flow chart of another HARQ feedback method according to an exemplary embodiment of the present invention. This embodiment is described from the perspective of interactions between a UE and a base station. For clearer descriptions of the interactions between the UE and the base station, this embodiment is described with reference to FIGURE 6. As shown in FIGURE 6, the indication information is carried in a PDCCH of a last eMBB data transmission, where the referral information can explicitly indicate that the URLLC data in a previous eMBB data transmission that prevails over an eMBB data transmission resource, or URLLC data that prevails over a position of the eMBB data transmission resource. As illustrated in FIGURE 5, the HARQ feedback method includes the following steps:

[0091] In step S501, the base station sends two eMBB data transmissions to the UE, where a time interval between the first two service data transmissions is less than a transmission latency in a non-HARQ feedback mode adaptive.

[0092] The indication information is carried in the program control data of a first transmission of subsequent service data.

[0093] In step S502, after receiving the previous eMBB data transmission, the UE reads the PDCCH of the subsequent eMBB data transmission to acquire the indication information.

[0094] In step S503, the URLLC data that prevails over the transmission resource is retained in a cache according to the indication information acquired, and HARQ feedback information from the eMBB data is generated.

[0095] The process for generating HARQ feedback information in step S503 is the same as the process for generating HARQ feedback information in step S302, which is not described here in any additional.

[0096] In step S504, the UE sends the HARQ feedback information from the eMBB data to the base station in a non-adaptive HAQR feedback mode.

[0097] In step S505, the base station retransmits the eMBB data that fails to be transmitted to the UE based on the received HARQ feedback information.

[0098] In the above embodiment, based on the interactions between the UE and the base station, the UE can acquire the indication information of the program control data of the first subsequent service data transmission, and recognize that the URLLC data prevails over the eMBB data transmission feature, such that the UE may not discard useful URLLC data during the transmission of eMBB data, and can correctly feed back the successful transmission or failure state of the eMBB data to the base station. In this way, the base station can relay the eMBB data that truly fails to be transmitted.

[0099] FIGURE 7 is a block diagram of an HARQ feedback device according to an exemplary embodiment of the present invention. The HAQR feedback device is arranged in a UE, and includes a receiving module 71, a holding module 72, and a sending module 73.

[00101] In this embodiment, a first service imposes a higher request on time for a second service, and therefore the first service data can prevail over the first service data. The first service can include, but is not limited to, eMBB, and the second service can include, but is not limited to, URLLC.

[00102] When the UE receives a first service data transmission from the base station, the indication information can be carried in the program control data of the first service data transmission, wherein the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data, or the second service data prevails over the position of the transmission resource of the first service data. When the UE receives the first two service data transmissions from the base station, the indication information can be carried in the program control data of a first later service data transmission, where the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data, or the second service data prevails over the position of the transmission resource of the first service data. Program control data can include, but is not limited to, a PDCCH. It should be noted that in the latter case, a time interval between the first two service data transmissions is less than a transmission latency in a non-adaptive HARQ feedback mode; and otherwise, before the program control data of the first subsequent service data transmission comes, feedback information HARQ needs to be sent to the base station. That is, the UE needs to send the HARQ feedback information to the base station before receiving the indication information.

[00103] The retention and generation module 72 is configured for the second service data that prevails over the transmission resource in a cache according to the indication information carried in the program control data of the first service data transmission received by the receiving module 71, and generates HARQ feedback information from the first service data.

[00104] In one embodiment, when the indication information explicitly or implicitly indicates that the second service data prevails over the transmission resource of the first service data, the retention and generation module 72 can be configured to: retain all data that fails to be transmitted in the cache, identify the first service data that fails to be transmitted from the retained data, and generate HAQR feedback information based on the first service data that fails to be transmitted.

[00105] The sending module 73 is configured to send the HARQ feedback information generated by the retention and generation module to the base station.

[00106] When the indication information is carried in the program control data of the first subsequent service data transmission, the sending module 73 can be configured to send the HARQ feedback information to the base station in the non-HARQ feedback mode. adaptive.

[00107] In the above embodiment, upon receipt of the indication information carried in the first transmission of service data, the second service data that prevails over the transmission resource in the cache, such that the second useful service data may not be discarded during the first transmission of service data.

[00108] FIGURE 8 is a block diagram of another HARQ feedback apparatus according to an exemplary embodiment of the present invention. As shown in FIGURE 8, based on the embodiment as shown in FIGURE 7, the retention and generation module 72 may include a first generation 721 sub-module or a second generation 722 sub-module.

[00109] The first generation 721 submodule is configured to generate HARQ feedback information based on a transmission success or data failure state other than the second service data that prevails over the transmission resource.

[00110] The second generation sub-module 722 is configured to adjust a transmission success or failure state of the second service data that prevails over the transmission resource as a transmission success, and generates the transmission success or information failure state HARQ feedback of all data in the first service data transmission.

[00111] The HARQ feedback information can be generated in a plurality of ways. For example, HARQ feedback information can be generated based on a transmission success or data failure state other than the second service data that prevails over the transmission resource. For example, a transmission success or failure status of the second service data that prevails over the transmission resource can be set as a transmission success, and the HARQ feedback information is generated according to the transmission success or failure status. of all data in the first service data transmission.

[00112] In the above embodiment, the HARQ feedback information generated by the first generation sub-module or the second generation sub-module can correctly reflect the success of transmission or failure status of the first service data, such that incorrect UE operations can be prevented .

[00113] FIGURE 9 is a block diagram of an apparatus for sending indication information according to an exemplary embodiment of the present invention. The apparatus is arranged in a base station, and includes an inference module 91 and a determination and shipping module 92.

[00114] Inference module 91 is configured to infer whether second service data prevails over a first service data transmission resource.

[00115] The first service can include, but is not limited to, eMBB, and the second service can include, but is not limited to, URLLC. A first service imposes a broader request on time for a second service, and therefore the first service data may take precedence over the first service data.
